Lee's duties as a Senator for NSW and a portfolio holder for the Australian Greens require her to travel both within NSW and interstate. Senate related travel is paid for using parliamentary allowances.

As Australian Greens spokesperson for democracy Lee has long campaigned for more scrutiny of how MPs use allowances and for this information to be made public as close to real time as possible.

Greens animal welfare spokesperson Senator Lee Rhiannon has called on the federal Minister for Agriculture to refuse permission for the export of up to 60,000 sheep by owners of Emanuel Exports that has had one of its export licenses suspended over investigations into systemic animal cruelty.

“Media reports that an owner of Emanuel Exports is applying to use the license of its sister company EMS Rural Exports to ship up to 60,000 sheep straight into the most dangerous of the northern hemisphere summer months are alarming,” Senator Rhiannon said.
